Amazon, Apple, Comcast, Meta, Microsoft, Nvidia, Union Pacific Railroad.

They all shoveled money to Trump's ballroom — and could win big from friendly treatment from the admin on active antitrust deals and lawsuits.

MSBuild tip: if you're working with binlogs, set the environment variable MSBuildLogPropertyTracking=15.

It enables logging of where each property was initially assigned from during evaluation and lights up more features in the binlog viewer.
